About Me

Systems diagram

I’m a software developer with a passion for building reliable systems and practical tools. I enjoy solving problems, improving workflows, and creating software that makes sense.

Software caught my attention when I was a kid. I taught myself C and C++ and spent a lot of time taking things apart just to see how they worked. That curiosity never went away.

I spent more than twenty years in Army Aviation. It was a long detour and it taught me a lot, but I always knew I would come back to software. Eventually I decided it was time to finish my degree and return to the work that actually feels like home.

Today I focus on C#, .NET, backend development, and practical tools that solve real problems. I like clear logic, predictable behavior, and software that makes sense. This is the work I enjoy and the work I plan to keep doing.
